Came back to the game 4th time and now I got to the end.
Very lovely visuals, good music, very cool animations and controls. I had no problems with jumps (though I guess it could be explained somehow that there is no double jump but you just add a momentum to your jumps firing down at the right timing, I got it right from the beginning, but just because I noticed how shooting push you back a bit)
Overall it feels insanely good, if not considering that it's too short.
The only problem I had, and why I finished only on my forth time - sometimes when you enter the doors, you get spawned under the map, or something like that. I mean, every door entering there are chances of you end up dying and loosing all the money. I think I died once after getting out of the trash container too. I was also able to get to places I was not supposed too and died by falling off the screen, but it's okay considering the time restrictions of the jam.
And yeah again, I really liked controls and that jumping system. Loved the elevator too, tho it seems it's not possible to bring it back down if you fell from it while on top.
Played in the browser, so maybe this is where all the bugs come from
